What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business, used to identify your marketplace for tax purposes. Whether you're operating a service marketplace, product marketplace, or B2B platform, an EIN is often necessary.
